CA 2234277

Scanning welding heads are introduced through respective openings of a workpiece into the workpiece by respective welding robots. When a laser beam is emitted from a laser beam emitting device, the laser beam is applied to a beam splitter of one of the welding robots, which reflects about 50 % of the energy of the laser beam and introduces the laser beam into a scanning welding head. The beam splitter passes the remaining 50 % of the energy of the laser beam therethrough. The laser beam that has passed through the beam splitter is reflected by a totally reflecting mirror of another scanning welding head. The scanning welding heads apply the laser beam to respective regions in the workpiece to weld the workpiece.

Têtes de soudage à balayage introduites par les ouvertures correspondantes d'une pièce à travailler par les robots soudeurs correspondants. Le rayon laser d'un dispositif émettant des rayons laser est appliqué à un diviseur de faisceau d'un des robots soudeurs, qui reflète environ 50 % de l'énergie du rayon laser et fait entrer le rayon laser dans une tête de soudage à balayage. Le diviseur de faisceau transmet les 50 % restants de l'énergie du rayon laser à travers lui. Le rayon laser qui a traversé le diviseur de faisceau est reflété par un miroir à réflexion totale d'une autre tête de soudage à balayage. Les têtes de soudage à balayage appliquent le rayon laser aux régions correspondantes de la pièce à travailler pour souder cette dernière.
